FASTENING-SUPPLYING MECHANISM.

Specification of Letters Patent.

Patented Nov. 11, 1919.

Original application filed December 16, 1914, Serial No. 877,596. Divided and this application filed April 25, 1918. Serial No. 230,750.

To all whom it may concern:

Be it known that I, WILLIAM H. BORDEN, a citizen of the United States, residing at WVinchester, in the county of Middlesex and State of Massachusetts, have invented certain Improvements'in Fastening-Supplying Mechanism, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to fastening supplying mechanisms for use in connection with fastening driving machines and particularly to supplying mechanisms for handling protectors of the type known to the trade as tadpole protectors. These protectors,

' which are designed to be driven into the soles or heels of boots and shoes, have each a head portion comprising laterally extending wings shaped to embrace the stock into which the protector is driven and a shank depending from the head between the wings,

a protector of this type being shown in United States Letters Patent No. 889,383, granted to S. D. Leland, June 2, 1908.

It is an object of the present invention to provide means adapted to receive the protectors in bulk and operative to arrange them with their wings similarly positioned and to maintain them in this position rela V tively to each other while they pass to driving position.

In furtherance of this object, there is provided an assorting device for positioning the protectors on the raceway with their shanks projecting into the slot of the raceway and their wings extending uniformly in one direction. Means are also provided for maintaining the protectors in the said position as they pass to driving position. Preferably the raceway itself is so constructed as to perform this function of maintaining the protectors in the position described.

Inasmuch as the protectors are delivered in quantity upon the upper end of the races way, it occasionally happens that they will lodge improperly on the raceway and move alonv' the same. Accordingly, there is piroe vide an improved kick-off device to remove such misplaced protectors. Preferably said device is mounted independently of them way and bears upon the upper side thereof.

This application is a division of application Serial No. 877,596, filed December 16,

1914, for improvements in fastening insert f ing machines.

' The above-mentioned and other features of the invention will be understood from the following specification which discloses in connection with the drawings one embodiment of my invention.

Figure 1 is a front end elevation of the upper part of the machine with the movshown, for convenience, as applied to a nailing machine of the type shown and described in United States Patent No. 490,624 dated Jan. 24, 1893.

In the drawings, the swinging frame 6, the

foot plate 7, the driver bar 8, the awl bar 12, the rotatable hopper 13, the separator lever 15, the means for actuating the driver bar and the and bar, the means for imparting lateral movement to the frame 6 that the and may feed the stock, and means for rotating the hopper and for actuating the lever 15, may be substantially as shown and fully described in said Patent No. 490,624.

To enable protectors having depending shanks to be controlled and driven by the machine referred to, a novel raceway is provided. v This raceway comprises front and rear walls or-plates 17, 18, with an assorting a continuation of the face of the rear wall 18 of the raceway. The upper end of the front wall 17 is separated quite a distance from the rear wall 18 by spacing blocks 22, so that the shank of a protector can freely enter the passageway between said walls, with the underside of the laterally extending wings of its head resting upon the edge of the front wall 17, the passageway being not wide enough to permit the head of the protector to pass therethrough. The upper end of the front wall 17 is beveled on opposite sides from a sharp to a gradual bevel, as shown in Figs. 2, 3 and 4, so that it is impossible for a protector to hang upon said front wall unless the-shank of the protector projects into the passageway between the front and rear walls, consequently only those protectors will be positioned properly which dro from the shelf 21 with their shanks pro ecting downwardly and with the laterally extending wings of their heads projecting away from the assorting device 19. All of the other protectors, namely, those which drop from the shelf head first or with their laterally extending wings projecting toward the assorting device, will engage the beveled portion of the front wall and be deflected into the hopper. The rear wall 18 of the raceway is slightly higher than the front wall 17 and is adapted to be engaged by the outer side of the head of the protector, so as to prevent the protector from turning as it travels down the raceway with its shank projecting into the passageway and with the underside of its laterally extending wings resting upon the edge of the front wall. The front and rear walls of the raceway are held together by screws 23, spacing blocks being interposed between the walls to determine the width of the passageway. At the extreme upper end of the raceway, resting upon the front wall 117 is a block 25 which is fastened to the assorting device by screws 26, as shown in Fig. 1.

The raceway near its upper or receiving end is provided, see Fig. 2, with a contracting device, herein shown as a plate 27 adjustably secured by suitable screws 28 to the rear wall 18 of the raceway, said device being made adjustable to enable the width of the raceway groove which receives the shanks of the protectors, to be varied. B adjusting the plate 27, the width of the raceway groove at the entrance thereto may be made to correspond to the thickness of the shank of the protector, so that only those protectors will pass through the entrance to the raceway which present the edges of their shanks to the groove of the raceway, thus causing the protectors to occupy a position on the raceway with the under sides of their heads resting on the top of the wall 17 and with the wings of the protectors extending in the same direction.

Bearing upon the raceway near the contracting device is a kick-off, shown in Figs. 1 and at as a lever 29 pivoted on screw 30 in the stationary part 32 of the hopper, a suitable spring 33 acting to keep the longer end of the kick-off normally pressed against the upper side of the rear wall 18 of the raceway.

The raceway is connected to and reciprocated with the swinging frame 6 as the latter is moved to effect the feeding of the stock. As the raceway is reciprocated any protectors having their shanks but partially in the raceway groove, or any protectors which are lodged improperly on the raceway, are struck by the kick-off and dislodged from the raceway.

Having described my invention, I claim as new and desire to secure by Letters Patent of the United States 1. In a machine for driving protectors having depending shanks, a raceway comprising front and rear walls spaced apart to receive and guide the shank of a protector, the rear wall of the racewaybeing adapted to engage the rear portion of the head of the protector and the front wall being adapted to sustain the underside of the head of the protector.

2. In a machine for driving protectors having depending shanks, a slotted raceway having mounted near the upper end thereof an ad ustable device that is adapted to control the entrance into the slot in the raceway below said device of only those protectors which have shanks of the desired thickness.

3. In a machine of the class described, a raceway for fastenings, a hopper in which the raceway is movable, and a kick-off sustained independently of the raceway and bearing on the upper side of the raceway, and operative on movement of the raceway to dislodge fastenings improperly supported on the raceway.

4. In a machine of the class described, a raceway, a hopper in which the raceway is movable, a kick-off bearing on the upper side of the raceway, and yielding means for keeping the free end of the kick-off seated on the raceway, said kick-off being operative on movement of the raceway to dislodge fastenings improperly supported on the raceway.

5. In a machine of the class described, a

and means for preventing the entrance into said slot of the shanks of any protectors which, upon leaving the shelf, have their wings projecting away from the shelf.

7. In a machine for driving winged protectors having depending shanks, an inclined shelf for sustaining the protectors, a

slotted raceway for receiving the protectors as they drop from said shelf, and an assorting device for positioning the protectors on the raceway with their shanks projecting into the slot and their wings extending in a uniform direction.

8. In a machine for driving winged protectors having depending shanks, a slotted raceway constructed to receive and guide the shanks and sustain the undersides of the heads of a series of protectors, said raceway acting to keep the protectors with their wings extended in the same direction.

9. In a machine of the class described, a movable raceway having a slot to receive the shanks of protectors, a shelf, an assorting device arranged opposite said shelf, and a kick-0E arranged to operate upon move ment of the raceway to dislodge protectors improperly placed on said raceway, substantially as described.

In testimony whereof I have signed my name to this specification.

WILLIAM H. BORDEN.
